WHAT IT DOES

What pointcloud_align_2d does on Pointcloud

AI agents invoke pointcloud_align_2d to trigger actions in Pointcloud. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why pointcloud_align_2d needs a policy

Based on the tool name, this likely performs a 2D alignment/registration operation on point cloud data, which would be a computational operation (Execute) that transforms/modifies data in memory or on disk. However, with an empty description, confidence is low. Alignment could be Write (modifies a file) or Execute (runs a computation).

From the tool's definition Tool name 'pointcloud_align_2d' on a point cloud processing server; description is empty and uninformative.
